DRAFT-TUBE FOR SODA-VVATER.

SPECIFICATIQIT forming part of Letters Patent No. 332,731, datedDecember 22, 1885.

Serial No. 162,611. (X0 model.)

T0 at whom it may concern; I

Be it known that I, J osnrn G. MILLER, of Chelsea, in the county ofSuffolk and State of Massachusetts, have invented an Improvement inDraft-Tubes for Sodaater, of which the following is a specification.

This invention relates to draft tubes wherein provision is made fordischarging streams of different sizes and of greater or less force, soas to agitate the main body of soda-water first drawn into the glass, bychanging the main stream so as to produce a small sharp stream, wherebythe sirup placed or drawn into theglass may be thereby thoroughly mixedwith the soda-water subsequently drawn therein; and it consists in theconstruction, combination, and arrangement of the several parts of thedraft tube, as' hereinafter more fully described, and specifically setforth in the annexed claims.

Figure 1 represents a vertical sectional elevation of a draft-tubeembodying my invention. Fig. 2 represents avertical section of a portionof the same with the interior tube raised upward. Fig. 3 represents anelevation of the interior adjustable dischargetube removed.

A represents the horizontal arm, provided at one end with a collar,screw-thread, and screw-nut, by which it may be secured to the marbleslab or other vertical support in such manner as heretofore employed forthe purpose. Said arm is provided with an axial passage, B, in the usualmanner, which communicates with the passage in the supply-pipe, that maybe coupled to the said end of the horizontal arm A in any desiredmanner. The outward end of the said horizontal arm A is likewiseprovided with a screw-thread, by which the body portion E of thedraft-tube is secured thereon by means of an opening in one side thereofprovided with a corresponding screw-thread, as shown, or as may bedesired. The said body portion E is provided with a vertical passage, C,leading from the opening or inlet-passage B, formed in the saidhorizontal arm A at its connection within said opening formed in theside of the said body portion E, and terminating within the seat D,formed within thetop opening, provided with ascrewthread, F,adjacenttothe said seatD,surrounding the interior vertical chamber, H, as shown,The said seat D is provided with an elastic washer or packing, G, uponthe top of which is placed the metal washer K, upon which the lower endof the screw-threaded spindle M rests and has a hearing, so that whenthe said spindle is rotated by the hand-wheel N the screw-thread uponthe lower end of the said spindle operates within a correspondingscrew-thread formed within thebody of the adjustingcollar I, the lowerend portion or extension ofwhich is provided with an externalscrew-thread adapted to connect with the said screw-thread F, formedwithin the walls surrounding the top opening formed within the upwardend portion of the said body of the draft-tube E, as shown. The saidadjustingcollar P is also provided with a smaller upward projection, J,provided with an external screw-thread, upon which is providedascrewthreaded capping-nut, R, provided with an elastic packing-ring, O,and metal washer Q, through which the body portion of thespindle Moperates as it is rotated or screwed up and down in opening, closing,and operating the valves, as hereinafter described.

To the lower end of the said body portion E is secured, by means of ascrew-thread, a sprayingnozzle, S, having a rlarge internal opening, asshown, and against the walls or sides of which the soda-water is ejectedor thrown from the horizontal openings T, formed through the sides ofthe lower portion of the small interior tube, U, the lower end of whichis formed with a very small opening, V, and the upper end is soldered orpermanently secured tothe lower end of the said screwthreaded spindle M,and provided with inlet passages or openings Z, formed horizontallythrough the sides of the sameatapoint within said surrounding chamber H,so as to permit the soda-water to enter said openings Z, (when the saidpassage C is opened, through the movement of the said hand-wheel N, inthe direction to remove the pressure from the said elastic packing G,)so that the pressure .of the aerated or soda water will force the samefrom its seat sufficiently to permit it to pass into the said chamber H,and thence into the said openings Z, formed in the said actuating-tube IHaving thus described my invention, what 5 I claim is- U, and downwardin the same to the openings T, near the lower end thereof, and outwardtherefrom horizontally, and striking or impinging against thesurrounding sides of the said spraying-nozzle S, and thence downwardtherefrom into a tumbler or other receptacle, as desired. Now,when thedesired quantity of soda-water has been thus drawn, and it is desirableto agitate the same and stir up and mix the sirnp previously drawn orplaced in the bottom of the glass therewith, so as to form the beveragedesired, the said hand-wheel is rotated so as to draw the said connectedtube U upward, which vertical movement of the said tube U carries thesaid lower openings, T, into position with the contacting snrfaceof thesurrounding bottom portion or wall of the said passage Y, so as to closethesaid openings T, and thereby prevent the outward passage of thesoda-water therefrom and cause the same to be forced through the verysmall opening V, formed in the extreme lower end of the said tube U,whereby a fine sharp stream is produced, as desired. The verticalopening through the bottom portion, Y, of the said body portion E formsa packingjoint with the exterior of the said discharge-tube E, so thatwhen the said small tube U is drawn upward, it being fitted to fill thesaid opening through the portion Y closely, the holes or openings T arethus closed, and the soda-water thereby forced through the very smallopening V, as above described, and shown in Fig. 2.

l. The drafttube E, having an inclosed chamber, H, and contractedpassage Y, and provided with an adjustable interior tube, U, having aninlet, Z, connecting with said chamber, and a large outlet, T, and smalloutlet V, whereby the upward movement of the said tube U closesthe'large outlet T, and thereby forces all of the discharge through thesmall outlet V in the end of the interior tube, as described, and forthe purposes set forth.

2. The combination, with the draft-tube E, having a chamber, H, andcontracted passage Y, of the adjustable interior tube, U, adapted to fitand slide within said passage Y, and provided with an inlet-opening, Z,outlet-opening T, and small hole V,.and a spraying-nozzle, S, as setforth.

3. The combination, with the draft-tube E, having an internal opening,H, and contracted passage Y, of the adjustable interior tube, U,provided with an inlet-passage, Z, outlet-passage T, and small outlet V,said passageT being closed by contact with the walls of said passage Yby vertical-movement of the said tube U, whereby the discharge isforcedthrough the small outlet V, as described.
